Question

The pressure of a gas in a 40 l container is 1.5 atm at 300K. When the volume is reduced to 20 l, the temperature decreases to 250 K. Calculate the final pressure of the gas in cm-Hg.

Answer

From gas laws p1v1/t1 = p2v2/t2 
Substitute the values of what the quantities are initially 
In the 1's and the final quantities in the 2's 
Find p2 

Ull get it in atm 
1 atm = 76cm of Hg
So let's say u got x atm 
X atm =x multiplied by 76 cm of Hg 
Do the math
